Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Cooling engine for motor cycle water water-cooling structure of the present invention, its overall structure is see Fig. 4, comprise (right side) crankcase cover 1, cylinder block 2, cylinder head 3, cylinder head 4 and cooling waterpump, be provided with cooling waterpump installation cavity on crankcase cover 1 surface, cooling waterpump to be installed in cooling waterpump installation cavity and by water pump cover 11 capping.In cylinder block 2, be provided with circulating water cavity 21, circulating water cavity 21 is connected with water pump cover 11 by engine water tube 5.See Fig. 6, be provided with a water passage hole communicated with circulating water cavity 22 at cylinder block 2 upper surface.See Fig. 7-9, be provided with water cavity runner 31 in cylinder head 3 inside, cylinder head 3 lower surface is provided with the water passage hole 32 communicated with water cavity runner, the water passage hole 22 of cylinder block upper surface and the water passage hole 32 position correspondence of cylinder head lower surface.Between cylinder block and cylinder head, be provided with sealing gasket, sealing gasket is provided with water passage hole to be communicated with by the water passage hole of the water passage hole of cylinder block upper surface with cylinder head lower surface.The cylinder head water outlet 33 communicated with water cavity runner is provided with at cylinder head 3 upper surface.See Figure 10-12, the cylinder cap water inlet 41 docked with cylinder head water outlet 33 is provided with at cylinder head 4 lower surface, cylinder cap water inlet 41 is communicated with cylinder head side and near the water outlet 43 of cylinder head upper end by the coolant flow channel 42 of cylinder head inside, coolant flow channel 42 vertically arranges the oil circulation passage also in cylinder head, to cool machine oil simultaneously.Water outlet connects motorcycle radiator by water pipe, and radiator outlet is communicated with the cooling waterpump installation cavity on crankcase cover surface by water pipe.
Water outlet final for motor is arranged in cylinder head by this structure, arranges cooling path on the one hand, extend circulation waterway in cylinder head; Be beneficial to structural design on the other hand, because the conventional construction size to cylinder head of water outlet design on cylinder head has requirement, the too little design of size is comparatively difficult, and this structure goes for the design of various engine cooling mechanism; Also achieve the cooling to cylinder head cocycle machine oil simultaneously, be conducive to reducing oil temperature, thus reach reduction engine temperature, improve the object of each component lubrication condition.
For convenience of cylinder block processing, and just circulating water cavity is thereon shaping, and described cylinder block 2 is made up of cylinder block body 23, cylinder block left cover 24 and cylinder block right cover 25 3 part, and the water passage hole 22 in cylinder block is arranged on cylinder block body 23, sees Fig. 5.Horizontal die cavity is respectively equipped with in the cylinder block body left and right sides, before and after cylinder block body, both sides are respectively equipped with horizontal front and back circulatory flow, are respectively equipped with the die cavity corresponding with the die cavity of the cylinder block body left and right sides inside cylinder block left cover and cylinder block right cover simultaneously.Cylinder block left cover is mounted by means of bolts on the left of cylinder block body, and the die cavity on the left of the die cavity in cylinder block left cover and cylinder block body surrounds and forms left circulatory flow.Cylinder block right cover is mounted by means of bolts on the right side of cylinder block body, die cavity on the right side of die cavity in cylinder block right cover and cylinder block body surrounds and forms right circulatory flow, and left circulatory flow, right circulatory flow join end to end to form described circulating water cavity with front and back circulatory flow respectively.This structured loop water cavity is polymorphic structure, has put up with cylinder block body self shape-designing die cavity on the one hand, and on the other hand, polymorphic structure is conducive to extending the flow path of cooling water at circulating water cavity, thus reaches better cooling effect.
Cylinder block right cover is provided with water nozzle, and water nozzle communicates with circulating water cavity, and circulating water cavity is connected with engine water tube one end by this water nozzle.
This engine water air-cooled structure except the right crankcase cover of Fig. 4 and water pump above identical with traditional water-cooled except, block structure adopts as Fig. 5,6 structures, cover about cylinder block being designed with cylinder block, about cylinder block, lid and cylinder block (body) form a special-shaped circulating water cavity, water nozzle in cylinder block right cover is connected with water pump cover by Fig. 4 engine water tube, forms water circulation.
As Fig. 6 cylinder block upper surface has a water passage hole, circulating water flows out thus through cylinder block, and enter in cylinder head water cavity passage from the water passage hole of Fig. 8 cylinder head lower surface of correspondence and circulate, and enter in the cylinder head cover as Figure 11 from the cylinder head water outlet of cylinder head upper surface.Circulating water enters cylinder head cover from cylinder head cover water inlet and enters motorcycle radiator circulation from water outlet outflow again.
Each parts that this water-cooling structure cooling path relates to have successively: right crankcase cover 1---cooling waterpump---water pump cover 11---engine water tube 5---cylinder block right cover water nozzle---circulating water cavity 21---cylinder block upper surface water passage hole 22---head gasket water passage hole---cylinder head water outlet 33---cylinder head water inlet 41---cylinder head internal cooling runner 42---cylinder head water outlet 43---radiator of cylinder head lower surface water passage hole 31---cylinder head water cavity runner 31---cylinder head upper surface---cooling waterpump installation cavity.
What finally illustrate is, above embodiment is only in order to illustrate technological scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technological scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
